Donaldson Water Absorption Filters

Donaldson® water absorption filters quickly and effectively remove free water from hydraulic or lubrication systems. Using super absorbent polymer technology with a high affinity for water absorption, Donaldson water absorption filters alleviate many of the problems associated with water contamination.

APPLICATION SIZING

To estimate the number of filters of a particular model, first estimate the amount of water in your system using equation (1): where VH2O is the estimate of the volume of water in liters, Voil is the volume of oil in your system in liters, and ppm is the concentration of water in your system measured using Karl Fisher titration (usually found in your oil analysis report).

Then calculate the number of filters required using equation (2): where N is the number of filters required and C is the maximum expected capacity of the filter from the table above. Make sure to use correct units as identified above.
